O projeto w1700k-sdr desenvolveu um firmware e um conjunto de utilit\u00e1rios que transformam o roteador sem fio Gemtek W1700K Wi-Fi 7 em um sistema de r\u00e1dio definido por software (SDR), capaz de receber e analisar sinais de r\u00e1dio em uma ampla faixa de frequ\u00eancias. O c\u00f3digo foi escrito em C e Python e \u00e9 distribu\u00eddo sob a licen\u00e7a MIT, exceto pelo m\u00f3dulo do kernel, que \u00e9 fornecido sob a GPLv2.<\/p>\n

Ap\u00f3s a substitui\u00e7\u00e3o do firmware padr\u00e3o, o w1700k-sdr reprograme o chip de r\u00e1dio MediaTek MT7996 para capturar sinais de r\u00e1dio arbitr\u00e1rios, n\u00e3o restritos a canais Wi-Fi. O SoC Airoha AN7581 usado no roteador \u00e9 acionado para o processamento inicial de dados do chip de r\u00e1dio e para envi\u00e1-los a um computador externo conectado via Ethernet de 10 gigabits por UDP, com uma taxa de at\u00e9 320 milh\u00f5es de amostras por segundo (Msps). No computador, os dados s\u00e3o analisados e visualizados por meio de gr\u00e1ficos e espectrogramas.<\/p>\n

O firmware foi criado do zero sem a utiliza\u00e7\u00e3o de c\u00f3digo propriet\u00e1rio da MediaTek, mas com a utiliza\u00e7\u00e3o de c\u00f3digo do driver mt76, que \u00e9 fornecido sob a licen\u00e7a BSD. O firmware inicializa o chip de r\u00e1dio autonomamente e o controla atrav\u00e9s de comandos do host. Em vez de uma vincula\u00e7\u00e3o r\u00edgida a canais, foi implementada a capacidade de ajustar o heter\u00f3dino para qualquer frequ\u00eancia nas faixas de 2.081-2.748 GHz, 4.647-7.509 GHz e 4.707-7.576 GHz com passos de 2,98 Hz ou 11,9 Hz. A frequ\u00eancia pode ser alterada em tempo real com um atraso de cerca de 1 ms. <\/p>\n
